Description

A mech built for the fire ninja

Kai is one of the original Ninjago ninja and is known for his fire element, which shows directly in the mech's colours: red dominates the outer shell, backed up by black, a pearl gold for accents and a light grey for technical details. At 323 pieces, the mech is compact enough to finish in one sitting, while its 118 unique parts still give it enough detail to feel like a proper model. The EVO label points to a simplified, more accessible build, a style used across several newer Ninjago sets.

Four minifigures for more play scenes

With four minifigures included, this set offers noticeably more characters than most single-mech sets of this size. That makes it possible to use the mech as part of a small scene with several figures rather than on its own, whether that's Kai facing multiple opponents or working alongside allies. For collectors building up a Ninjago shelf, the figure count is a real plus, since it allows small scenes to be acted out without needing extra sets. Younger fans in particular are likely to see the larger cast as a clear advantage over a plain vehicle set.

Mechanical detail versus part count

The ratio of 118 unique parts to 323 total pieces shows that the mech includes a fair number of special shapes for joints, weapons or cockpit elements alongside the standard bricks. That mix is typical of mech builds in the Ninjago range, where mobility and a recognisable silhouette matter more than sheer size. Combined with the grey and gold accents, the finished mech reads less like a simple toy and more like a piece of stylised armour.

Matching colours across Kai sets

All 118 parts are listed on this page with their colour and quantity, which is useful for tracking down red or gold elements specifically, whether to extend the mech or combine it with pieces from other Ninjago sets. Because Kai appears across several waves of the range, the colours in this set often line up well with both older and newer Kai-themed builds.
